[FIXED] Just updated Ubuntu to 22.04, now I can't open Jupyter Notebook

Issue

When I try to launch Jupyter Notebook, the browser launches and I get the following error:

Access to the file was denied

The file at /home/benjamin/.local/share/jupyter/runtime/nbserver-11758-open.html is not readable.

It may have been removed, moved, or file permissions may be preventing access.

I tried running

jupyter lab clean --all
pip3 install jupyterlab --force-reinstall

as per the suggestion from here: Jupyter Notebook: Access to the file was denied. The commands ran, but I still get the Access to the file was denied error. Also, on the reinstall command it spits this out:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 4.2.5 requires pyqt5<5.13, which is not installed.
spyder 4.2.5 requires pyqtwebengine<5.13, which is not installed.
conda-repo-cli 1.0.4 requires pathlib, which is not installed.
anaconda-project 0.9.1 requires ruamel-yaml, which is not installed.
spyder 4.2.5 requires jedi==0.17.2, but you have jedi 0.18.1 which is incompatible.
spyder 4.2.5 requires parso==0.7.0, but you have parso 0.8.3 which is incompatible.
sphinx 4.0.1 requires Jinja2<3.0,>=2.3, but you have jinja2 3.1.1 which is incompatible.
sphinx 4.0.1 requires MarkupSafe<2.0, but you have markupsafe 2.1.1 which is incompatible.
python-language-server 0.36.2 requires jedi<0.18.0,>=0.17.2, but you have jedi 0.18.1 which is incompatible.
fermipy 1.0.1+5.g5a57 requires astropy<4, but you have astropy 4.2.1 which is incompatible.

which may or may not be part of the problem.

Solution

UPDATE: I am able to access the notebook now by using the URL printed to the console. (just copy and paste it into the Firefox browser)

I would still like to figure out how to get it to open with just the 'jupyter notebook" command the way it used to work before the update, but for now this is a useful workaround.
